   The issue has been resolved with some limitations. Inbound and outbound calls are now connecting successfully. However, VoIP encryption was disabled to restore phone service. We are continuing to work with Cisco to resolve the encryption issue on the secondary circuit and restore encrypted voice communications. Until encryption has been restored, credit card merchants should not accept payment card information over the phone.
